Increased abuse and diversion of prescription opioids has been a consequence of the increased availability of opioids to address the widespread problem of undertreated pain. Opioid risk management refers to the effort to minimize harms associated with opioid therapy while maintaining appropriate access to therapy. Management of these linked public health… (More)

Phenylpiperazines, such as meta-chlorophenylpiperazine (MCPP) a serotonin agonist, have recently been reported to block conditioned avoidance responding (CAR) in the rat, which is an indication of possible antipsychotic utility. Since MCPP is a major metabolite of both antidepressant drugs trazodone (TZ) and etoperidone (ET), both were examined for activity… (More)

Generally, antipsychotic agents are dopamine receptor blocking agents that also block conditioned avoidance responding (CAR) in the rat. Recently, however, both (Q-methoxyphenyl)piperazine (OMPP, 1h) and (m-chlorophenyl)piperazine (MCPP, 1o) have been reported to block conditioned avoidance responding in the rat although neither has dopamine receptor… (More)

Recently, we reported on a series of arylpiperazines 4 which exhibit high affinity for the serotonin 5-HT-1A and 5-HT-1B binding sites. Although these compounds interact weakly with dopamine D-1 and D-2 receptors, they are reasonably potent in inhibiting conditioned avoidance responding (CAR) in the rat, an indication of potential antipsychotic activity.… (More)
